no potential across the neon, so it goes out. A downside of this Ingeneous

Funnily enough, we have one circuit with two compact fluorescents on it
(nearly the same, apart from the white powder! :-)). It has one of
these neon visibility things on the switch and it still seems to work OK
(there are no incandescents in the circuit).

Don't know WHY, mind....!


A large R across the fluorexcrescent?

More than likely the neon is connected across L & E.
